PRIORITY CLAIM

This U.S. patent application claims priority under 35 U.S.C. § 119 to: India Application No. 202021038985, filed on Sep. 9, 2020. The entire contents of the aforementioned application are incorporated herein by reference.

TECHNICAL FIELD

The disclosure herein generally relates to industry monitoring, and, more particularly, to a method and system for sustainability measurement in an industrial environment.

BACKGROUND

There are various factors which affect sustainability of any industry. For example, in a banking/investment industry, a challenge is to track the sustainability impact created by entities such as companies, and institutions in a more standardized/uniform manner comparable with peers, and which can be aggregated at higher levels. The sustainability impact is reported in highly individualistic, textual reports inhibiting one-to-one comparability, quantification and aggregation. This is more complex as the reporting is often suggestive, pursued as an image building, and nice to have rather than being obligatory. This makes the data disparate, non-uniform and non-standardized. While more social accountability is enforced on entities of all kinds with respect to sustainability, the reporting is yet to mature and to be standardized despite various standards and formats existing. Hence, any institution pursuing assessment of sustainability of its clients is fraught with challenges of data availability, standardization of metrics and apple to orange comparison difficulties.

FIG. 2 is a flow diagram depicting steps involved in the process of performing the sustainability measurement by the system of FIG. 1, according to some embodiments of the present disclosure. At step 202, the system 100 collects a plurality of documents containing organizational data and/or any additional data that may be required for the sustainability measurement. Based on parameters such as but not limited to level and quality of source from which the data is collected, the system 100 may calculate/compute a data quality score which indicates quality of data being fed as input to the system 100. The ‘levels’ and ‘quality’ of sources may be determined and pre-configured with the system 100. For example, the data level may be at least one of a) company level data, b) parent/group level data, c) peer group level data, d) sector level data, and e) no data f) Geography level data (Viz., Country, Region etc.,). Similarly, each data sources may be classified into one of High, Low, and Medium classes, based on pre-defined quality standards. For example, sources such as but not limited to subscribed sources, data partners, published reports, and websites of Pre-determined types and so on are classified as having ‘High’ quality, and a source score of 3. Similarly, sources such as but not limited to association websites, and news websites are classified as having ‘Medium’ quality, and a source score of 2. Further, sources such as but not limited to social media and other such sources are classified as having ‘low’ quality , and a source score of 1 is assigned. In similar manner, different data levels (alternately referred to as levels) also are defined and pre-configured with the system 100, along with a level score. For example, company level data are assigned a level score of 4, group level data are assigned a level score of 3, peer group level data are assigned a level score of 2, sector level data are assigned a level score of 1, and no data is assigned a level score of 0. The system 100 may then calculate the data quality score as:

Data quality score=data source score*level score  (1)

After determining the data quality score for all data being collected as input, the system 100 may consider having data quality exceeding a set minimum threshold of quality, for further processing. At this stage, the system 100 sets appropriation logic for Indicators at targeted/desired levels, based on feasibility of data available. For example, if the targeted level is either project or transaction and the indicator data feasibility is at Company or sectoral levels, standard norms and parameters are pre-defined and algorithms set to appropriate the indicator value to the desired level. It may be noted that the indicator value may be acquired in full or in granularity.

The system 100 may be configured to separately process each of the plurality of documents using one or more appropriate technique, at step 204 for extracting the organizational data from the extracted documents. For example, the system 100 may use NLTK sentence tokenizer from an NLTK natural language toolkit to split contents of each document into a plurality of constituting sentences. For a document d with a set of n sentences, denoted by S and a set of indicators I with cardinality m (where m denotes the number of unique indicators), the system 100 finds a subset of most relevant sentences s⊂S corresponding to each indicator c∈I. It may be noted that information about an indicator may be present in terms of related concepts in arbitrarily complex ways inside a document written in natural language.

From the document being processed, consider a sentence having ‘x’ number of words and an indicator having y number of words. The system 100 generates (206) a first matrix ‘A’ of suitable dimensions, where each row of A is a vector representation for each word of a sentence obtained using a suitable technique, for example, a 100-dimensional Glove embedding technique. In order to reduce the effect of stop-words in each sentence, the system 100 replaces (208) each raw of A with corresponding vector representation.

The system 100 then generates (210) a second matrix ‘B’ of suitable dimensions (for example, B may be a (y+1)×100 matrix) where 1^(st) to y^(th) rows of B correspond to the embeddings of words in an indicator and the (y+1)^(th) row is obtained by taking a tuple-wise average of the constituent word embeddings. Further, the system 100 generates (212) a (y+1)×(x) Similarity matrix ‘C’ where each entry c_(ij) in C is computed as a function of cosine similarity between a sentence word x_(i) and an indicator word y_(j).

The system 100 then calculates (214) a similarity score between the indicator and a sentence is calculated as:

Score=((maxC)^(T)*(W))/(y+1) where D ^(T) denotes transpose of a matrix D  (2)

Where maxC is a column matrix of size (y+1) obtained by applying Max function on each row of a matrix C and W is also a column matrix of size (y+1) obtained by computing significance of indicator words in a page by using their term frequencies and distribution across pages. The similarity score for each sentence-indicator pair indicates/represents extent of similarity between the sentence and the indicator. Based on the similarity score calculated for each sentence-indicator pairs, a n×m matrix is generated where each entry denotes the similarity score between the sentence s and the indicator c calculated by using equation (2).

Further the system 100 extracts (216) features/feature vectors from each of the plurality of sentences. A sentence matrix M of order n×f contains the features for every sentence of a matrix. Here ‘f’ denotes the number of features. A few examples of features that are extracted by the system 100 are, but not limited to, a) Similarity score vector, b) Numerical Presence, c) Date feature, d) Units of measurement, and e) Sentence length. Definition of each of the features is given below:

-   -   Numerical Presence—A sentence in the document is said to be         important for an indicator if there is a presence of         quantifiable information in the sentence which can be identified         and counted using Named Entity Recognition. The system 100 is         configured to utilize numeric named entities such as but not         limited to money, percentage, cardinal, date, quantity and         ordinal numbers. The system 100 may use any appropriate         technique (for example, SpaCy's Named Entity Recognizer (NER))         to locate and identify numeric named entities from each         sentence. The system 100 may be further configured to use         One-hot encoded vector of numerical classes as a feature.     -   Date Feature—Presence of date named entity in the sentence can         also determine the relevance of the sentence. The system 100 is         configured to assess importance of each of the sentences based         on type of information in the sentence. For example, the         sentences which contain futuristic information as well as past         information may be classified by the system 100 as sentences         having least significance, and the sentences having mentions of         current time instance may be considered by the system 100 as         sentences having high significance. Based on the determined         significance of each of the sentences, the system 100 assigns a         date feature sore (P) for each sentence. by considering the         following conditions:         -   P=2, if the sentence contains current year information         -   P=1, If the sentence contains past year information         -   P=0, If the sentence contains future year information     -   Unit of measurements—Let L be the list of units of measurements         used for the indicators. Presence of unit of measurements is one         of the factors deciding the relevancy of the sentence, as         presence of the unit of measurements in a sentence indicates         presence of numerical information in the sentence. The system         100 creates one hot encoding for each sentence where ‘1’ denotes         the presence of corresponding unit in a sentence.     -   Sentence Length—The system 100 determines the length of each         sentence by counting the number of words in the sentence.

The system 100 then identifies (218) at least one indicator matching each of the sentences, based on the calculated similarity score and the extracted features. At this stage, the similarity score and the features indicate to the system 100 relevance of each sentence. The system 100 may use a feed forward neural network classifier to classify the sentences into one of the existing indicator categories, or as ‘Others’ if the sentence is not found to be relevant for any of the categories. The system 100 may use a mufti-layer perceptron with single hidden layer and softmax output layer as a classifier. The input layer takes as input the feature vector. The output layer uses the softmax function to classify the input sentence into one of the existing indicator categories or others if found not relevant. Each of the indicator categories has a specific sustainability measurement associated with it. As part of the sustainability measurement, the system 100 identifies an indicator category majority of the sentences are associated with. Further, based on the sustainability measurement associated with that particular indicator category, the sustainability measurement is performed at document level. Further, for the sustainability measurement at an organizational level, the aforementioned process is performed at the organizational level. At this stage, the system 100 determines an indicator category majority of the documents collected from the organization are associated with, and based on the sustainability measurement of the identified indicator category, sustainability of the organization is assessed/determined.

In various embodiments, steps in method 200 may be performed in the same order as depicted in FIG. 2 or in any alternate order which is technically feasible.
